-## 🚧 IN PROGRESS: CLI Development (Phase 3)
+## ✅ COMPLETED: CLI Development (Phase 3)
 
-### CLI Requirements for Manual Testing
-- [ ] Book CRUD operations (add, edit, delete, list)
-- [ ] Author/Genre management (auto-create, list)
-- [ ] Location management (place, bookshelf, shelf)
-- [ ] Reading tracking (start, finish, rate)
-- [ ] Search functionality testing
-- [ ] Data import from old format
-- [ ] Loaning operations
+### CLI Implementation ✅ DONE
+- ✅ **Business logic separation**: Clean `services.py` module independent from web concerns
+- ✅ **Book CRUD operations**: Create, read, update, delete books with proper validation
+- ✅ **Author/Genre management**: Auto-create on-demand with many-to-many relationships
+- ✅ **Location management**: Place, bookshelf, shelf hierarchy with filtering
+- ✅ **Reading tracking**: Start, finish, drop, rate reading sessions
+- ✅ **Wishlist operations**: Add, remove, list wishlist items
+- ✅ **Advanced search**: pyparsing-based query language with field filters and comparison operators
+- ✅ **ISBN import**: Google Books API integration for book metadata
+- ✅ **Database utilities**: Status, initialization, seed data commands
+- ✅ **Output formats**: Human-readable tables and JSON for scripting
 
-### CLI Commands Planned
+### Advanced Search Language ✅ IMPLEMENTED
 ```bash
-hx book add "Title" --authors "Author1,Author2" --genres "Fiction"
-hx book list --location "my house" --shelf 2
-hx book search "keyword"
-hx reading start <book_id>
-hx reading finish <book_id> --rating 4
-hx loan <book_id> --to "Alice" 
+# Working CLI commands:
+hxbooks book add "Title" --owner alice --authors "Author1,Author2" --genres "Fiction"
+hxbooks book list --place "home" --bookshelf "office" --shelf 2
+hxbooks book search "author:tolkien genre:fantasy"
+hxbooks book search "shelf>=5 title:\"Lord of Rings\""
+hxbooks book search -- "-genre:romance"  # Negation
+hxbooks reading start <book_id> --owner alice
+hxbooks reading finish <book_id> --rating 4 --comments "Great book!"
+hxbooks wishlist add <book_id> --owner alice
+hxbooks book import 9780441172719 --owner alice  # ISBN import
 ```
 
+### Search Query Language Features
+- **Field-specific searches**: `author:tolkien`, `genre:"science fiction"`
+- **Comparison operators**: `shelf>=5`, `added>=2025-01-01`, `rating>3`
+- **Quoted strings**: `title:"The Lord of the Rings"`
+- **Negation**: `-genre:romance`
+- **Date comparisons**: `added>=2026-03-01`, `bought<2025-12-31`
+- **Multiple filters**: `author:herbert genre:scifi owner:alice`
+
+---
+
+## ✅ COMPLETED: Automated Testing (Phase 4)
+
+### Testing Framework ✅ IMPLEMENTED
+- ✅ **pytest infrastructure**: Database fixtures, isolated test environments
+- ✅ **CLI command tests**: All 18 commands with happy paths and error scenarios (29+ tests)
+- ✅ **Advanced search tests**: Parametrized tests for field filters and complex queries
+- ✅ **Query parser unit tests**: Type conversion, operator logic, edge cases (36 tests)
+- ✅ **Output format validation**: JSON and table formats for all commands
+- ✅ **Database integration**: Full CLI → services → database → relationships flow testing
+- ✅ **Error handling tests**: Invalid inputs, missing data, constraint violations
+
+### Test Coverage Achieved
+- **CLI Integration**: Book CRUD, reading tracking, wishlist operations, database utilities
+- **Search functionality**: String filters, numeric filters, date filters, negation, complex queries
+- **Parser robustness**: Edge cases, type conversion, fallback behavior, unicode support
+- **Database validation**: Relationship integrity, user creation, data persistence
+
+**Decision**: Migration tests deemed unnecessary for this simple personal app
+**Status**: 65+ tests passing, comprehensive coverage for critical functionality

 ## 📋 TODO: Remaining Phases
 
-### Phase 4: Search & Core Features
-- [ ] Implement proper FTS with new schema
-- [ ] Add faceted search (by author, genre, location)
-- [ ] Create search result serializers
-- [ ] Add pagination
-- [ ] Optimize query performance with proper indexes
-
-### Phase 5: Testing Framework
-- [ ] Set up pytest with database fixtures
-- [ ] API endpoint tests
-- [ ] Search functionality tests  
-- [ ] CLI command tests
-- [ ] Migration tests
+### Phase 5: Search & Core Features Enhancement
+- [ ] Full-text search (FTS) integration with SQLite
+- [ ] Search result pagination and sorting
+- [ ] Boolean operators (AND, OR, NOT) in search queries
+- [ ] Parentheses grouping: `(genre:fantasy OR genre:scifi) AND rating>=4`
+- [ ] Search performance optimization with proper indexes
+- [ ] Autocomplete for field values (authors, genres, locations)
+- [ ] Search result highlighting and snippets
+- [ ] Saved search management improvements
 
 ### Phase 6: GUI Rework
 - [ ] Update templates for new data model
